OIL-PRESS MAT.

SPECIFIOATION forming part of Letters latent N0. 758,57 5, dated April 26, 1904.

Original application filed September 10, 1901, Serial No. 74,906. Divided and this application filed June 26, 1902. Serial To all whom it may-concern.-

Be it known that I, ROBERT F. WERK, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Oil-Press Mats, of which the following is a full, clear, and exact description.

This invention relates to oil-press mats; and the subject-matter of the present application is a division of an earlier application for Letters Patent filed by me on September 10, 1901, Serial No. 74,906.

The highest grade of mat now in general use is made from I camels hair; but camels hair is objectionable, because it packs and felts together when in use to such an extent as to hinder the free flow 0f the oil, and the yield per ton of seed is greatly reduced by reason of this felting of the camels hair. The oil is compelled to seek an outlet on the sides where there is no cloth to hold the seed or meats from being washed out into the receiving-tanks, which deteriorates the quality of the oil. Oamels hair also stretches from onefifth to one-third of its original length, which is objectionable, as this requires the cloth to be out too short to start with, and before it isworn out it has stretched too long for convenient handling. All these objections are overcome by the use of horsehair, and the horsehair being soft it retains all the good features of camels hair. I

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of an oil-press mat embodying my invention, and Fig. 2 is a lon-' gitudinal section on the line 2 2 of Fig. 1.

The press cloth or fabric consists of longitudinal warp strands or threads A and the weft strands or threads B, the latter extending across the warp-strands and interwoven therewith in a manner to be concealed or protected thereby. In the present invention the warp-strands and the weft-strands A B, respectively, are essentially made of long animal hair which is soft and pliable.

(No model.)

The hair is selected and prepared so that it may be spun or twisted together into a strand or thread of the desired length and thickness, and in the production of the threads I prefer to make the weft B of greater thickness than the warp A.

The hair which I use in the manufacture of the mat may be horse-tail hair or cattle-tail hair or hair from horses Inanes; but in each case the hair must be soft and pliable, and it is preferably quite long for convenience in spinning or twisting the hair into the threads or strands.

To produce the mat or fabric, the warpthreads A are arranged longitudinally side by side and in the same transverse plane, while the weft B extends transversely across the warp and is interwoven therewith. As shown by Fig. 1, the warp-threads greatly exceed in number the'weft-threads, and I may use from five to eight times as many warp-threads as there are weft-threads in the fabric. The weft-threads may be produced by doubling or folding them into parallel lengths, which are suitably spaced apart; but the weft-threads may be of separate or continuous pieces, as desired and according to the dimensions of the mat. The close arrangement of the warpthreads prevents the passage of the seeds between them, thus reducing the pressure of the seeds upon the weft-threads, and the increased number of warp-threads as compared with the weft-threads is advantageous,because the pressure is more evenly distributed. The weftthreads of increased thickness secure a desirable cushion for the warp-threads when the mat is subjected to pressure in the operation of using the same.

The use of animal hair in the manufacture of the mat imparts the desirable drainage for the oil, and the product is entirely free from sediment, so as to obviate the necessity for subsequent filtration. The durability of the mat is secured by the use of long animal hair, and the improved mat is very pliable and affords the desirable cushion, so that the article will not break or tear lengthwise when subjected to pressure, and the mat can be folded upon itself Without breaking at the line of fold or in number persquare inch, and the Weft- IO crease. threads being thicker than the Warp-threads. Having thus described my invention, I claim In testimony whereof I have signed my name as new and desire to secure by Letters Patent to this specification in the presence of two sub- An oil-press mat or cloth consisting of warpscribing Witnesses.
